This base consists of a single piece of metal that attaches directly to the rifle's receiver, providing a sturdy and secure platform for the scope to be mounted on. The 1 Piece Base is known for its simplicity and ease of installation, as it eliminates the need for aligning multiple pieces and ensures a solid connection between the rifle and the scope. This type of base is popular among hunters and shooters looking for a reliable and durable mounting solution for their optics.
